A new Facebook app promises to help users 'clean up' their profile, removing incriminating posts - and could be highly useful for party-loving students facing job interviews.
The app, 'Facewash', was designed by three students at the American Kent State University, and can scan and hide embarrassing posts in seconds.
It's free to use within Facebook, and automatically scans Facebook Timelines for items that users might want to hide or delete.
The app scans not only posts but also photo captions, comments and links that have been 'Liked' via Facebook.
By default, it's set to scan for obcene words, but users can scan for other terms that they might wish to hide or delete before others view their profile.

Words pop up highlighted, and users can then decide whether to delete the posts.
Facebook's upcoming 'Graph Search' function has raised further concerns over the site's privacy policies - offering the ability to search other people's Timelines using their 'Likes'.
Online privacy activists the Electronic Frontier Foundation have described Graph Search as 'creepy' and say, "this new search allows strangers to discover information about you that you may not have intended them to find."
